Plane formula counterpunch board 3a, Fig. 4 shown in Fig. 3 is shown that material occurs with counterpunch board 3a after rotor 2a accelerates
The process of collision and relation, wherein carried out to crusher chamber 1a, rotor 2a and counterpunch board 3a simplifying representing, O represents crusher shaft
The heart.Material enters inside rotor 2a, and two granules are fallen counterpunch board by rotor after being dished out by high-speed rotation that rotor 2a is counterclockwise
A, B 2 point of 3a, now rotor 2a turns over certain angle, and two granules move out along straight line, its direction of motion with turn
The angle of sub-radius is typically equal or close, i.e. general α ≈ β, and its value can be obtained by experiment or emulation mode.Correspondingly,
Two granules collision angle corresponding when A, B 2 of counterpunch board 3a that fall is respectively α 1, β 1.
Move after a segment distance, collide with the impingement area 31a of counterpunch board 3a, diverse location impelling material out with
The collision angle of impingement area 31a is the most different, such as α 1 and β 1.
On the basis of analysis material collides feature with counterpunch board 3a, inventor is by experiment repeatedly and emulation point
